In such cases, the determination or decision should be reopened only where the net effect of the reopening would be favorable to the claimant. Ultimately, the sum total effect of the reopening must be favorable to the claimant,
i.e., give him or her something he or she did not have before the reopening. Reviewers
should make sure this is what happens. Therefore, before reopening any determination
or decision under this rule, the effect of such reopening must be analyzed carefully.
